Hi
first of all, sorry for my not perfect english

I have a fan site, about Michael Jackson, you can see it here www.mjj.it
in this month we are developing a new version, new graphics, new information
part of this developing is maing a wiki
I already installed a wiki engine on my site, and use it (is onlya  work in progress wiki, no public acces at the moment... we never publich the address anywhere) you can see it here www.wiki.mjj.it

we use it mediawiki... is fine for what we want to do, a wiki like wikipedia, with all the information about Michael Jackson world
we wan to put here as many definition about MJ... and for this i think mediawiki is really god

but... i found mediawiki is really hard to use...
for example i want to delete all the revision history (something like more than one mega for only 60 definition)... but in wiki media there isn't an automaticly way to delete them... on my hosting service i can't use shell... and there is no a administration panel


can you tell me a valid wiki for my project?
i need a wiki were i can have some user with the ability to wrote and modify a page (like wikimedia)...
a "last changes" pages, and other stuff like that

what do you think is good for such a wiki?
