Yes, GD is multisite ready.

You could add a slider plugin/widget below the header on relevant pages, where you add slides with links.

You can use the “Place Categories” and other “Custom Post type categories in the WP menu settings if you want to build your own menu.

The “popular” category widget will show the categories with most listings in order of “popularity” with users adding listings.

Julie, about the password saving incorrectly, that is not a problem itself.
Once you save your password, the password field in admin will always only show 8 characters regardless of the length of your real password, but your password will be saved correctly.

For the update problem, Stiofan will be able to help if you post the details Paolo asked for.

I can see only one map on your listings/category pages and that is the GD Listings map …

Correct, you need to have all the latest core AND addons. That is the only way they are guaranteed to work together, and we only support up-to-date installations.

If there is an update for core but not for the addon, then that means that there was no need to change anything in the addon because nothing in core affects the addon.

And always update core before updating addons.

Thanks for letting us know.
