I've been working on a few changes to the site for the last week or so and I've just put them live. Other than a few bug fixes the main changes are:
New PM system
PM's work slightly differently now. I think of them as private threads rather than private messages as such, and now you can invite more than one person to take part in them.
You can now also delete these threads quickly and easily from the main PM page, here.
Once you have deleted a thread it really hides it from you rather than deleting it, so if anyone else responds to the thread it will come back so all the 'invitees' can see it.
Custom Items Per Page
Now if you edit your profile, you'll see there's a drop-down for Items per page. This allows you to set how many forum posts/threads etc you want to be able to see.
As with the whole of the site, your feedback is gratefully received. Hope you all like these changes!
