Is that normal, like do I need a minimum of posts or are there some other requirements -
Or is this some kind of bug ?

You need about 5 or 7 rep. It's a measure against spam.

you need to have 10 rep to post links

You need to learn the secret handshake first,

Ah, thats good to know, thank you. :)
That was really bugging me. xD

You need a certain amount of rep before being able to post links, I believe 5 points are enough.

Edit: Ninjaha'd.

Would you teach me the secret technique sensei ?
For I am your humble disciple.

it involves breaking the fingers of a scammer

You sure? It used to be 7.

Ah, Grasshopper, when you can snatch the pebbles from my hand - and replace it with beer - then you will be ready to link!

*edit* As a point of note: you get +1 rep per day (as long as you make at least one post). You can also gain rep if people upvote your posts. So you may learn the secret handshake sooner than you anticipate.

Bring me one ad it shall be done. ;)
I`m all out of beer. :`(

it was 10 for me
but im sure catnip will be able to tell us soon enough

Wanted to post something, its the wrong topic, sorry. >.<

Wouldn't be the first time a thread has gone off-topic. In fact, I'd argue that is rather more common than actually managing to stay on topic for over a dozen posts.
