This isn't an answer but I can't stick in the comments. (If there is a better way moderator, please let me know).
Here's the steps I did for the second account, which works fine. repo, repo2 and testdocs are in the root folder.
Log into usera account
Open Terminal and....
MacBook:/ usera$ svnadmin create repo2
MacBook:/ usera$ chmod -R a+rwX repo2
MacBook:/ usera$ cd testdocs
MacBook:testdocs usera$ svn import file:///repo2 -m "initial import"

Committed revision 1.
MacBook:testdocs usera$
Then I opened repo2 in svnX. All files are there. I log off of usera and logon to my account. I had already done the above but with "repo". Those are the results I've already posted, which show import not working. I open repo2 with svnX. All files are still there. I open repo with svnX. No files. Why does it work in one account and not in another?
