Last night I posted about me beginning the creation of a brand new BBCode parser which had the potential of allowing nested tags… Of course it has been done 
But I myself haven’t done it, until now!
After working on the new function for hours (And adding ~320 more lines of code) I am getting really close to finishing the new product which allows nested tags! XD. I have yet to test how fast it is because it isn’t fully finished, but it is getting there! However, I am quite sure it will be much faster than the older one because it just used regex to find tags on the message, one after another, and regex on a huge message isn’t that fast.
I hope to finish this tomorrow! As long as I don’t run into any major problems.
