Joomla/Website Fixes Urgent

Issue 1. Users are saying they are NOT receiving automatic activation emails upon registering (typically yahoo/hotmail accounts). This is coming from a Joomla and PHPProbid installation. We have tried using text-only emails but it has not helped. Issue 2. Paragraphs on our Joomla template using MyBlog extend beyond borders and it does not look correct, example: [login to view URL],com_myblog/show,[login to view URL],70/lang,en/ Issue 3. Font color of MyBlog component is incorrect, it is dark grey, but instead should use the same white font the rest of the site uses. Issue 4. On SMF forum, at [login to view URL],com_smf/Itemid,26/board,1.0 I want to remove automatic linking of www.example.com. For example, if the user types [login to view URL] it will not automatically become a hyperlink, unless the user specifically types http:// beforehand. Issue 5. Event’s calendar component for Joomla CSS/colors are messed up and need to be fixed to match our template. Example: [login to view URL],com_events/task,view_day/year,2008/month,07/day,16/Itemid,31/lang,en/
