Hi,

Showing his age in the profile while only fill in the date.

Yes this is possible, you can choose in date field the format to show, try to see "Display Type" parameter

Sending an email 2 months before a date that is set in a date field

You need to contact Acymailing support, they already have a plugin to do this, maybe with simple modification is possible.

So can acymailing filter on a field of Easy profile?

I don't think, but we not know potential of Acymailing filters. Our plugin only allow to get data from Easy Profile.

Show on prifile how many months are past since a certain date that is filled in the profile

Now in "Display Type" parameter we have only "Years Ago" option. You can edit /administrator/components/com_jsn/models/fields/date.php file to met your need:
- open file /administrator/components/com_jsn/models/fields/date.php
- from line 35 to line 38 you will find the code to return number of years (if you have choose "Years Ago" in "Display Type" parameter)
- replace this code with some code to calculate months*

* this require PHP knowledges

Thanks for all your clear answers.

I think it is weird that a button export all to csv or excel is not default stuff.
What if you want a list emails to send an email in mailchimp, what if you have a crm where you want to import stuff in.

But maybe i am wierd :-)

I really like the easyness of your extension.
But...
I go looking for other extensions.
