By default, the option for visitors to reassign a listing has been showing up for members on both the submit listing and edit listing pages. I feel this can be confusing on the submit listing page and people may end up generating new accounts and assigning listings to them when they don't read carefully. I can't think of any reason by a non-admin would want to reassign a listing during the submission process -- an admin would want to, and a member might want to reassign later when they sell a site but not during submit.
In the last few days: Changed WSN Forum's category names to use tags for better SEO. Converted the registration defaults to use a serialized array instead of the previous custom format, and added a helper function for changing a registration default. Did a lot of code refactoring for 9.2. Improved the details of parameters in backtraces in bug reports. Made a lot of progress on the ability for the upgrader to update templates and styles from a theme instead of from the standard. Hopefully this will be finished for 9.2.1.
Found a nice tool called browsera for detecting javascript errors and layout problems that are specific to Internet Explorer. Most of the time, WSN's template conditionals make things easy. There's a long-standing annoying case where they're buggy, though: checking whether a complex HTML field contains a term. Suppose you want to do This listing mentions a widget. If the description has HTML tags, the conditional can error because the closing tags in the HTML are taken as closing the conditional.
The biggest issue with using a custom theme is that it gets out of date. The bootstrap theme modifies the majority of the templates, so it's especially succeptible to this. I'm thinking about how to allow people to use themes without that drawback. Here's the plan so far. Each theme can include a special file that specifies a URL to get a theme-specific template schema. WSN's manage templates page and upgrade.php can then check that URL, which will return an array of standard uniqueness hashes for theme-customed templates.
Just released 9.2.0 non-beta, though as the experimental series it's always kind of beta. Most people will probably hold off on upgrading to 9.2 until there's a specific feature you want in it. Note that the 7.1 series is now expired, so the active series are 8.0, 9.0, 9.1 and 9.2. Really there's no reason to use 9.0 though, because the upgrade to 9.1 is easy and 9.1 is now the stable series. Discovered that the 'last post' link for threads in WSN Forum was getting cached to older pages of the thread when using Firefox.
