Coda is by far most the best Developer Tool I've ever used on a PC or a Mac. It simply concentrates all you need to develop web on a simple and cute window. Some of it's features that I like are the auto-completation, Multiple Site management, Preview , CSS Editor a syntax highlinting.

However the package doesn't stop just there! The guys at Panic (whom by the way are really cool guys I met em at the WWDC08) added SVN capabilities to this little monster software. SVN is really cool for large projects in which you need to control versions of your software so if various people are working on the same project codes don't mix up.

But well, lets get to the point ( thats what you are here for right? ). Today I tryed to add my own SVN respository to one of my Sites on Coda, however I just couldn't get it to work, it keep getting me the "certificate issued by untrusted issuer" or something like that. After googling for a few moments I came across this solution:

1. Open you Terminal an type:

svn list https://yourCoolSVNServer..com/source/project

2. Just as in SSH you'll be prompted with the question on whether you would like to accept this Certificate, temporaly, ignore it or accept it permanently.

3. Just use the (p) option and now it will ask you for your OS X password.

4. Boom ready.

All of this happends because not everyone can issue 100% trustable certificates so we have to tell our good OS X to trust them because we said so. =P

Hope this helps
