Thanks for clarifying the position I spent a couple of hours last night trying to work out what was wrong, when it appears nothing! Perhaps you could update your first post to explain the position as I see there's another poster on the other link with a similer issue and he does no is way around the N900, unlike me!, from his posts on Nokia discussions. Clealry it is down to each developer but now you have got your conversation modder working correctly perhaps it would be wise for the other theme developers to develope their themes to wrok with your modder so they can be easily intsalled by usuers like me?
I note your comments re the name issue and will therefore try it later with a theme which actually shows either "you" or my name as I don't think the standard bubble theme does but, if not, perhaps the developer could allow the selection of names as that's my favorite theme at present. Thanks for all your assistance
