Sorry for the delayed response.

One thing at a time.

CB Documentation subscription does not offer any support. It was devised as a means to get people to financially support the CB Team in order to continue funding the free - opensource Community Builder suite. The CB Team always had a donation button but this was rarely used. People would just download CB for free and never look back. People always need extra incentive to support free opensource projects. Thus the CB Documentation subscription was created. As described here , documentation subscribers get to download detailed CB documentation and extra bonus documents created from time to time and also get early access to release candidate CB Team releases as the CB Team deems appropriate. Also, CB Captcha is currently only offered to documentation subscribers. Currently, CB ProfileBook 1.2, CB ProfileGallery, Captcha 2.2, Autowelcome 1.2, Privacy plugin, Ratefieldtype plugin, ajaxtext field plugin are offered as RC packages for doc subscribers only.

CB Documentation subscription offers no support. Support is provided from the community and things are also monitored by CB Team members and site moderators. And personally, in my spare time I try and help out as many as possible giving priority to those that have the nice CB Docs icon in their forum posts (indication that they are CB Doc subscribers).

CBSubs is a commercial offering also offered on Joomlapolis. It is in no way connected to the CB Documentation subscription. Purchasing a CBSubs license give you a CBSubs license and download privileges for downloading the CBSubs package and CBSubs documentation. As CBSubs works with and requires CB 1.2, it is very useful to have detailed knowledge regarding CB 1.2 - so if you are not a seasoned CB 1.2 user, perhaps you should consider becoming a CB Doc subscriber also in order to download the CB 1.2 detailed documentation. Of course this is not mandatory.

Getting to your needs.

Sounds like you need the privacy plugin - this is currently in RC status and available for CB Doc subscribers. So if you want it, you need to become a CB Doc subscriber.

Groups can be managed with the GroupJive component which also works nicely with CB 1.2. For forum, you can download Kuena (there will be a cool CB-Kuena integration released by CB Team very soon - work in progress here). Comments to other profile is done with the CB ProfileBook plugin (1.2 RC offered for CB Doc subscribers).

You mentioned the MyCommunity template. This is also a commercial offering independent of anything else. You can purchase and download at any time if you want it.

Currently there is no official paid support service on this site for CB. The CB Team does take on various tasks on an adhoc basis for extra fee (hourly rates are quoted per case).

CBSubs and MyCommunity do have special support forums on this site and we try and address all questions as timely as possible. No SLA is given. We also provide professional services in this support area if requested to.

I hope this addresses some of your presales concerns regarding CBSubs and other not directly releated issues.
