The forum appears to be responding ok here as far as I can tell. If typing is very slow that's likely to be related to something on the local computer. To start with, I'd recommend:
1/ Do a spyware and virus scan of your system ( just in case, always good to check )
2/ Clear out your browser cookies in case you have a cookies problem which could cause you to have to log in each time.
3/ Try closing down any background programs before using your web browser to go to the forums, in order to check whether it relates to another application running at the time.
