(You have insufficient privileges to post here) , i can't post on Service sub-forum, and how am i supposed to get likes? (what are the meaning and the purpose of that?)
The purpose of requiring likes is to help curtail drive by spammers from coming in and spamming Digitalpoint and encourages new member to participate and become a part of the Digitalpoint community.
Don't become discouraged. I have seen many members become established with just one good post. In fact I have received as much as 6 likes from a single post on several occasions. I even received 18 in one day. It's easy, just contribute, get involved and before you know it you're in. Offer advice, give critique and don't be afraid to use humor if applicable, good luck to you with all.
