Email notifications loading very slowly

Hello,

I've recently set up email notifications from EasyDiscuss which I'm really pleased with- thanks!

The only problem is that in Outlook, they are loading incredibly slowly and often crashing the whole thing... This is not the case for email notifications from EasyBlog, so I figure it must be a file of files within EasyDiscuss which are causing the problem. Have you heard of this sort of problem before? Do you have any idea where I could alter the html (ie compress it so it loads faster) or something similar?

Thanks very much!
