Probaly this http://forum.ragezone.com/f425/follow-system-global-675059/ tl;dr Right click to follow someone, if they press yes on the request sent it should look something like this I guess.
Interesting. I've always wanted a follow option. It would ease me in kpq and lpq for self-leeching. It would also ease goby sellers (at least in old source), where the gobies stray off course because of the buyer. However, I feel like this option does not fit well with MapleRoyals. MapleRoyals support native multiclients, whereas Maplestory doesn't. Some computers can handle up to 6 clients. Some of us have more than one computer. Imagine if you had 11 characters following 1 and the characters are all mules. Sorry if I'm mistaken and only 1 character can follow another at a time. I'm worried of potential abuse. If the follow option is tweaked a bit, I'd like to see it introduced as well.
I mean it's pretty black & white what it does, you click to follow someone & it does just that. If I recall you weren't allowed to have a pet out so i'm not quite sure what could be abused about it. Also this featured kinda sucked (imo *) but I agree with your last statement, if it were added I would love to see a more fluid follow system like how RuneScape's follow feature is, where you don't copy EXACT movement right as it's done, rather a second after.
