post something that someone on the forums likes.. i.e a good reply, good information.. something funny even and you will end up with likes.
The clue is in the word "like" you need to post something you think someone else will like...it's as simple as that...
Giving out advice that is useful is the #1 way to get likes. Also good humor will get you them too. Another way is to get involved in the discussions that happen here. If you do then a member may agree with what you wrote and give you a like. Good luck with this.
Your wrote should be interesting, and something funny, Check to see these https://forums.digitalpoint.com/help/established wish there were other members to give like for you.. Cheer up!
