It's not that simple. One makes friends here a bit the same way as in real life.
Watch people's posts and replies long enough to get an idea of their values, thoughts and how they express themselves. If you see someone that interests you, check out their profile; it may or may not contain information that is important to the potential or otherwise for friendship.
If you're after sex, remember most women here don't want it and will strongly object to your approach.
If your English is not good, you might find greater difficulties because language is vital to friendship.
@Chankam You're welcome. Probably most people wouldn't quibble about it, but if you want to be fluent in English, it would help to memorise the rules for using the apostrophe. Hope you begin to discover your potential friends soon. :)
