yum as root question

[Benjamin Sher <delphi123 zebra net>]

Dear friends:

My yum is now working fine as root. But I am wondering about the past. 
I've been running my new installation for several weeks, and I've been 
installing programs with yum as User instead of as Root. How has this 
past installation affected or will affect the current status of yum on 
my computer? It's working fine, I've installed several more programs 
(this time as root), but has my past mistake in any way corrupted or 
messed up the yum database? If so, what would you recommend that I do?

Thank you.

Benjamin
