Well Anja, for one, Lycos s*cks bigtime in terms of running Joomla and such. Lycos has got his servers shut so much that you cannot do anything with normal ease as you are able to with Joomla.
My advice, get a decent hoster. I am on Routhost.com, a decent hoster with a big filespace and a lot of bandwith for a good price. And there are many more who are cheaper and better. Sorry to disappoint you with this, but I would like to save you the trouble by mentioning it now.
