How do I...? and other questions

I hhave had an Activity set up for a while and I have received a request to join my activity.  How do I admit them?  My activity is set up as 'AAny iRecord user can request to join but an activity administrator must approve their membership'.  If I click on the &(1 pending) members on my Activity page I just get a link to the iRecord Home page with recornt sightings added.   I have added members in the past - is this something that has changed after the update last week?

I've got an irecord account running OK on my desktop. Just installed the app on my iphone, but it won't accept my desktop log ins. Surely I don't need to set-up another account? please help!

If there is a problem with our account, we need to have a way fo contacting an administrator, but I cannot find any such available other than this.

There are two ways to use iRecord:

1) Through the internet browser
2)  Through the Android App.

Bizarrely, I cannot sign into the Android App, despite being able to do so through the internet browser.   Failed to Fetch is the error message.
