In answer to your questions:
- This would either require customization of the theme, or you could look at one of the plugins in the
AppThemes marketplace called
MapPress which may offer what you're looking for.
- The advanced search functionality can be found on the category view page, shown in the sidebar as "Refine results" (as shown in the
ClassiPress demo). You can determine which custom fields are used for this search.
- By default, ClassiPress requires users to be registered before they can post an ad. It would require customization of the default theme if you wanted to allow registration-free posting.
- This is not a default feature of ClassiPress, so again this would require customization on your part.
- You can get an idea from the
ClassiPress version history page, with an indication of future releases from the
theme release status page.
- This ultimately relates to WordPress and the hosting setup you have, rather than ClassiPress specifically. For a majority of users, there aren't any special requirements needed to run their site without any concerns of this nature, however for very high traffic sites, you may like to read some of the
High traffic tips for WordPress to get a better idea of how to manage it. Thanks.
