we're using XOOPS for several sites within the organization, i.e., one XOOPS installation for every site.

some questions:
1. is there a way of categorizing/tagging or relating data across all XOOPS installations? for example, if one site has a link in the mylinks module that relates to 'poverty' and there is another site that has a different link that also relates to 'poverty', can we do something on XOOPS so that we could relate these two links?

2. we are using retrievalware/convera as our enterprise search engine. what should we do to get it to search a XOOPS site? (this could be related to my first question above)

3. are there consultants/firms out there who do enhancements on xoops-based sites?

1. Not per standard, no

2. I am not familiar with retrievalware/convera, so cannot answer this one

3. Yes, we are quite a few making a part- or full-time living off XOOPS consultancy. We don't have an actual listing of consultants apart from the Developers catgory in web links (and some in other categories, too, I think.
