Thank You

I noticed that it left a list of "TeraWURFL" tables in MySql so I removed all of them. I just wonder if there is anything else to remove. The extension installed well on 1.5.26 and looks like it would work well, and it did detect and display my site "mobily" but my template didn't work well with it an I don't have the time to tweak it so I may try it again someday, so for now I just want to make sure it's not using resources.

The message

means that corresponding extensions was removed from joomla's database by this time (e.g., maybe you tried to uninstall it till this moment).

I'd try to install/uninstall MJ again, maybe second time it will be uninstalled correctly.

Thanks you I find it beneficial for me
