Oh, quest ideas in the old forums. So hm. We’ve got…

Kneading the Dough http://tamriel-rebuilt.org/old_forum/viewtopic.php?t=24883
Premise: The player needs to go around to merchants in town and “persuade” them to pay their dues to the Baker’s Guild.
IMO: Mechanics of this one are a little strange. Who is the Mother Alessia and why are they responsible for collecting the dues? Especially if they are a failing business. I think we could turn this one into the Thieves Guild collecting “protection money” from all the shops in town, or just one shop, the baker’s shop, in particular. Player still has to run around persuading people to pay up, but the logic behind it works better. And throw in the baker’s shop to keep that lovely quest name…

A Donation http://tamriel-rebuilt.org/old_forum/viewtopic.php?t=24875
Premise: Imperial Cult member is asking for the player’s donation to help rehabilitate a beggar.
IMO: I really like this one, as it breaks the mold of quests being mainly for killing or exploring dungeons. I would suggest even going so far as to turn it into a series of quests for the Imperial Cult faction, where there are several beggars to help. Some need straight out gold donations, but others perhaps need the player to acquire other items to help them start a career. One beggar needs a set of cups and plates and some ingredients because they want to start a restaurant, one needs a set of Expensive clothes because they are applying for a job up at the castle, one needs a mining pick...etc, etc. Make use of some of those items in the game that have no real value otherwise.

Keeping Up with the Jannuses http://tamriel-rebuilt.org/old_forum/viewtopic.php?t=24306
Premise: Two Imperial aristocrats are competing over who can collect the most expensive (insert item here, probably Dwemer stuff). The player is to obtain one of these items and then choose who to sell it to.
IMO: I think the strength of this quest is in playing the two nobles off each other, and should then be focused on that instead of the fedexing the quest item back from a Dwemer ruin (which is pretty standard fair, and hence “meh”). So this could involve going back and forth between the nobles, perhaps playing tricks on them to get them to raise their buying price, blackmailing them with secrets the other noble provides you, etc, etc.

History of Ebonheart http://tamriel-rebuilt.org/old_forum/viewtopic.php?t=24293
Premise: If I’m reading this right...a scholar is researching Ebonheart history and wants the player to help them find evidence.
IMO: A quest very much needed, I think, especially as Ebonheart as portrayed in TESO as a Dunmer town AND there’s the confusing fact of the other Ebonheart across the Inner Sea. However I’m uncertain of how to pull it off, as I don’t know that much about Ebonheart history. As is, it sounds like a fedex quest and kind of meh. Exploring the underwater ruins out past the harbor might be an interesting edition. The player could also interview some Dunmer about the town, and get an earful of how they hate and/or like the town. Another possibility is talking to a ghost who has been haunting the castle…?

And throwing up this old idea of mine for consideration again:
The Clueless Egg-Miner http://tamriel-rebuilt.org/forum/old-ebonheart-east-empire-clueless-egg-...
Premise: An Imperial is trying to start up an egg-mine. They run into a few problems with this venture, namely getting an Indoril to sell them the landspace required, and obtaining kwama who don’t attack each other due to not being from the same colony.
