I use to use Siwftswitch all the time, main reason was to use the Swiftswitch chat. When I got mIRC I stopped using it as much and ever since I moved house. I've stopped using Siwftswitch all together, same with all chat servers
apart from forum rooms.
Nevermind why, its along story.
But my brother's still an Op on the main swiftswitch channel and owns the Rsmarket room.
Edit:
A friend of mine and me did a BIG discussion on aonther website and on the Siwftswitch chat room last year. About how Siwftswitch is not legal, many people just think it is. Because they don't understand how it runs and all that.
There are Jagex stuff mebers out there who also, say it is and isn't.
The one's who say it isn't, don't really have much of a clue what swiftswitch is all about and how it runs. Also they haven't even bothed to look into very well either.
Strider, the owner and creator of Swiftswitch has also talked about it and gone through it all on Runescape Community. The very same website were my friend and talked about it.
Its all up to you were you want to use it all not. Its 100% safe and my brother is a good friend of Strider.
Hope this helps.
