Sometimses the forum software interprets legitimate character strings as external links. You could try obfuscating them.I have tried to reply to a couple of posts but I get a message saying that I cannot post external links yet. Any ideas?
Links (Web Pages and Email Addresses)
Email addresses and URLs are not permitted until the author has accumulated sufficient forum posts (currently 20, but this can be varied according to the level of threat). This is a means of discouraging spammers, so that newbies can't put inappropriate content in public view until they have a history of being "clean". The forum software will reject any post which contains, or appears to contain, links.
