1. Is it possible to make a list of the items in a category ordered? For example, I could make an ordered list of tutorials. 2. Can I hide particular tabs Or information on a tab? - I know that you can limit who views attachments, however I would like to embed video or other information that is only viewable to certain usergroups. 3. Can I install more than one RM on one xenforo site (if used for very different purposes)?
