Would you give your first name?
yes, it's Thomas, but I usually just go by Tommy
Last name?
yes, it's the common English word for color described in hexcode as #000000
Age?
yes, I'm currently 22 years old...two moths until 23. >_<
Gender?
yes, last I checked, I had all the proper biological apparatus of the male gender. XD
Phone number?
not unless I know you IRL. :P
Address?
No full address unless I know you IRL, but I don't make any effort to hide the City/State I live in...it's Houston, TX if you were wondering.
Do you post pictures of yourself?
If I have one, yes. If you must know what I look like, search for my posts in the appropriate thread in OC. XD
Think of it this way. When you meet people in any RL organized social group, they can usually tell your name, age, gender, hometown, and appearance by default while your phone number and address are private unless you trust them enough to know it.
I see internet forums as no different than a RL social group in that regard, so I don't see the point in hiding my name, age, gender, hometown, or my appearance.
...and anyone who openly gives out their phone number or address online is just asking to be visited by a rapist. >_>
