Pastehtml.com, one of the sites multiple people use for logging, recently closed its doors do to an influx of scamming and sneaking. The owner wants the site to be used freely, but doesn't want it to infringe on the rights of others. The owner of the site has re-opened it, but is now requiring all users to be personally whitelisted.
If you go to the site currently, you can e-mail the owner with your reasons for using the site. He or she approved mine in about half an hour, so he or she is clearly okay with using the site to host logs.
If you've never used the site before, it's pretty amazing. I use it to host my combat and RP logs in full colour. It's a great tool, and I'm glad to have it back!
TLDR: Pastehtml.com is back up and running. Log in, email the owner to get whitelisted, and continue logging.
