Excuse me for bumpin' up this thread but...

If I would decide making a sticky feature, where would I begin and can anyone give me pointers how to code it? I'm not looking for people telling me to "Do it yourself" because I'm intending to do just that but I do need a hint where to begin and whatnot.

So, anyone out there able to tell me?

Also, I'm not interested to hear/read that a sticky feature is "unethical", "stupid" or whatever. That's your opinion, man. :)

Thanks in advance.
