I would say that a Wikipedia dedicated to Blockland Retail would be better, cause some / many things have changed.
And BLR is simply not RTB.
The RTB wiki IS for BLR, and RTB when it comes out for it. We've even got an announcement on the top of the front page saying we need to update everything for retail because v00002 is old news. The RTB wiki is for everything related to documenting Blockland, and by extension RTB. Modding, mapping, etc, playing the game, explaining some history. All that. Just the only Blockland stuff that the wiki isn't for is personal stuff like clans, individual people, their servers, etc.
Plus, you know who's in control of the wiki (RTB), so you can trust us with your data, and it will always be updated. Plus it works with everyone's accounts at the RTB forums, which is nice and easy. We put a lot of work into that wiki, I just think it would be a shame to scrap it all to host somewhere that's just trying to make some cash.
