As stated in the other thread, dungeon locations are deliberately not publicly posted, to encourage exploration and interaction with other PCs to locate them. If you're having trouble, feel free to ask around with people in-game - most will happily give directions to where something is located.
Relevel requests can be posted in the Relevel/Rebuilds forum, and unless your concept is drastically changing we typically approve them.
A map is pinned in the server's Discord in the general discussion channel. I don't recall if it's also posted somewhere on the forums, off the top of my head, but if it is I imagine someone will link it soon. I'd go looking for it but I sadly don't have much time left on my lunch break.
A wiki has been attempted to be started on multiple occasions but never gets off the ground. We just don't have enough interested people with the time or inclination to put the project together. What we do have is the Player Resources section here on the forums, and the /help command in-game, both of which are pretty thorough! If you do notice anything odd about the former, please post in Bugs - there are the occasional miss or glitch to fix. Also, always trust the forum write-ups over the in-game ones for things like feats, spells, etc, as the in-game ones are regularly out-of-date because editing the .tlk file is a pain.
In-game quests are mostly to get you started and help get your character up into the level 10-12 range, as that's when DM events really start; very few run events for lower levels than that. Keep an eye on the Announced Quest forum, for events in your time and level range - our DM staff is fairly active and new events go up on the regular.
Thank you Edge for Clarifying our suggestions and for giving us a better insight in the functions of the Guild, Thanks
