You had to fill in an application form? Where was this? Do I just volunteer in the laxest chairty there is? XD
I completely sympathise.
I have spent so long trying with charity shops, helplines, etc. In the end I just thought stuff them. I have got nowhere after a ridiculous amount of ringing, writing, emailing, chasing up, etc etc. A useful tip though is if it's on do-it.org it might be better to contact the organisation directly instead of through the website as that can delay it even more.
A good place to try is usually the local council for voluntary service (CVS). May be known by a different name locally but usually in the phone book.
Get details of charities looking for volunteers from them then contact charity direct.
Good to have a look round before saying yes to volunteering, some jobs may not suit all temperments.
We had a volunteer once who it turned out could not stand the client group (alcoholics, drug users, homeless and prostitutes) so we put her to work in the kitchen preparing food. She left after a short time as she didn't volunteer to peel potatoes or wash up all day.
Not a lot that could be done - but not everyone gets on with all sorts of people to the same degree.
Best thing to do is to just ring them or go in, keep reminding them you are still interested! they will get back to you in the end.
