Form = Forum
?'s means question
points = ponits
If you answer a question in a forum and the initial poster rewards you ponits you will get forum ponits. Your overall SDN ponits will be the summary of forum, blog, wiki etc ponits.
And by the way Netweaver Administrator is not the right forum for questions like these, you should ask them in the [Community Discussions|/community [original link is broken]; either in Suggestions and Comments or in the Coffee Corner.
