<ul>
<li>
Be sure to back up your data before using this feature.
</li>

We do not support (and cannot fully support) the creation of custom posts or display of data, so please use another plugin yourself. (We provide some shortcodes that support display.)
</li>
<li>
Custom fields do not disappear when you delete a custom post. They must be deleted from the database. (Use a plugin or database management tool to delete unwanted data.)
</li>
<li>
This plugin is not designed to handle large amounts of items (e.g. 10,000 items).
</li>
</ul>

Import Users from CSV

It does what it says, easy to use if used to databases. I did use it in an intallation with lots of user meta and it's behaving really nice.
Also the Exporter add on it's working nicely.
Thanks a lot!
