Thanks Paul for suggesting an instant messages in the forum.

Have added it to the whole site. Please let me know if there is a problem with displaying on mobile phones.

My only gripe with how it is on my PC monitor - still a semi-transparent text of "IM Mailbox" and other text below it, which interferes with my typing replies and the like. Its not a big deal really just a little irritating and means I have to undergo the agony of scrolling up/down a bit to see what I am typing

Would it help if it was moved up or down or over to the left?

It's not really a problem to be honest.
It interferes a little with replying to posts that's all. If it was moved over to the left side of the screen it would be better for replying to posts. It's just a preference thing really so no big deal.

My friend has added a module for pm, hope you like it

Yes Andrew that is way better!
