I thought I'd posted the list of Tiki Friendly Hosts but perhaps my wifi was on the blink...
Shared hosting is a bit restrictive for what we want to do at Geek.Zone anyway, so we are going to move to a VPS provided by BitFolk. If one is a hackspace or a similarly community friendly project they provide a VPS for free.
Since we are moving anyway, we very well may move from Tiki to WikiSuite. Is the migration quite easy?
