I haven't heard anything about it for about 22 days (that I can find, at least) and
http://wiki.returntoblockland.com/ still seems to be inaccessible. If it isn't coming back, then it's a real shame, because I really found it useful in several situations. If there has been any information on it, though, can somebody point it out to me?
If it's not coming back, I could try starting my own Blockland wiki this weekend, that is, if anyone would support it.
