As an extension to the way that webgroups are now integrated into Warwick Blogs, there has been a slight way to the way permissions work when you are creating an entry. You can now search for specific groups when creating an entry by clicking "Find a Group", which allows you to find students for a particular module or course on–the–fly.
Along with this, in the "Manage your Groups" page on your blogs Admin page, you can add groups to this also, so you can search for groups as well as users. These groups update automatically, so the people who are on the module "ES425" now are not the same who will be on it next year, so bear that in mind when creating the entry.
Update: We've also fixed a problem with posting special characters into comments with our nice new slide down AJAX comments
