"Sign" here if you want the Guild chat back on the site rather than discord!!!!
(my computer is so old and shitty it cant run discord yay!!!!)
Old Chat, while still around in the coding, isn't gonna make a comeback anytime soon. It was never fully reliable and some of the features that have been incorporated into discord have helped out the forum overall.
What I would suggest is making sure you have windows 7 and maybe run discord through your browser. If you're still having trouble and your PC is 10 years old then maybe you need to do a full cleanup invade you have bloatware or programs that are blocking the site.
