Should I Upgrade?

I already upgraded and It took about two seconds. No plugins harmed.
I think that everyone should upgrade because of the security problems in 2.8.1.

Did you update?

WordPress 2.8
First I’d like to announce the upgrade of orenyotmov.info to the WordPress 2.8 official version.

Now, if you are asking yourself if you should upgrade then the answer is really just a big plain YES.

Just do it.

Plugin Description

Mass Custom Fields Manager (MCFM) is a plugin I wrote in order to help people who use WordPress to manage their post’s custom fields with ease.
If you don’t want to spend your time editing each and every single post’s custom fields to the same value or you want to delete/update specific posts you don’t have another tool that let’s you do that.

Here is a screenshot of the plugins interface:

You can choose posts by category,ID,custom field value and more and with a click of a button manage their custom fields.
