Hello guys, since when I checked I tried to change my profile picture here forum but can not find the option, can someone guide me, I did not find any topic in explaining forum.
Profile Picture!
You need to gain a total of 25 points before you are allowed to change your profile picture. You can earn points by making posts that people agree, like, LOL, or insightful your post.
Hey there.
I believe you need 25 reputation points to change your profile picture.
You get one point everytime someone gives you an insightful, agree or like.
People will often give you them if you post something helpful or good.
Also, giving other users points will often lead them giving you some back. 
If you want to see how many points you currently have, I advice you to go to your profile and count together all the above mentioned reactions as the counter is bugged.
Edit: Too late!
@wolvie Faraleth mentioned that LOL points don’t count, even though they should.
Moderator @Amerika, you asked me not to put my post in bold? because I do not speak Portuguese and translator use there I get kind of confused by some translations!
Yes, please do not bold your posts. It’s not a huge issue or anything but it is a courtesy thing on the internet to not always draw attention to yourself over anybody else by using bold, colors etc. It’s similar to always using /me in IRC or typing in all caps.
Thanks for understanding!
