Can we avoid the name-calling, please?
Depending on the sort of access you have to your webserver (ftp or SSH), a Geeklog site can be setup in as little as 10 minutes (a little longer if you only have ftp access, mostly due to the time it takes to upload all the files). With a little tweaking, you should still come in on under an hour.
GL2 is still a long way away, so we can't tell exactly what the upgrade path will be. But rest assured that we will ensure that you can carry over as much of the data (stories, users, etc.) as possible. After all, we're all running Geeklog sites ourselves and want to keep our stuff intact, too ...
The forum, like almost any other plugin, uses Geeklog's permission system, so yes, you can have private forums for certain groups of users, etc.
Signatures are currently plain text only.
You may want to hop over to
opensourceCMS.com and try out Geeklog there (you can log in as an Admin user there, too). They don't have the forum installed, though.
We're still planning to set up a fully-fledged Geeklog demo site (including the forum and some other plugins), but haven't found the time yet ...
bye, Dirk
