The maintenance includes a 1 hour one on one Webex training session that is specifically for any questions/training you have. You may also attend the twice monthly group training sessions we do (those are open to any of our past clients and ask are informal question/answer). The calendar for the group sessions is available at https://ywm.eventbrite.com.
You can send us questions at any time as tickets and we will reply and make a tutorial for you. Tickets do count against your total ticket time.
We also have an extension tutorial knowledgebase available at http://yellowwebmonkey.com/joomla-tutorials
