Hi retniw18! I know your frustration well. I was interested in a community of sisters but there was very little info about them online. I emailed the address they had on their outdated website specifically for vocation inquiries. I heard nothing for about a month. So I called one of the other priests of their brother order, and he gave me a sister's contact info. I emailed and left a phone message. Nothing.
I gave up for a while, but a spiritual director got me moving again, and with much persistence I did manage to establish contact with this order, and then I visited them, and now I'm entering in October and I'm very happy about it. :) I have to say, though, their bad email/phone habits have continued. It took months after my visit before I had a straight answer to the question of whether I could enter and when-- not because they were trying to decide whether to accept me, but because I had to go through the formality of talking with a few people, and the simple task of getting in touch with those people was very difficult. I was getting up at 4:30 am to call overseas several days in a row and still couldn't catch the person I needed!
It was very discouraging sometimes to have to wait and wait for answer after I'd put myself on the line asking for entry. Inconvenient too, because if I'd been given an entry date sooner I'd have had longer to prepare. Nevertheless, I'm so glad things have worked out.
In my discernment I've found that a LOT of orders are very bad at answering inquiries. There was one I totally wanted to visit. They said I could visit for two weeks and sent me a very detailed 12-page application. I completed it right away and sent it off registered mail. I know someone signed for it, but I never got any reply and that was the end of my contact with them. I now believe they weren't God's will for me, but I do wish I'd visited just to know what they were like; it might have helped my discernment and at least it would have been interesting! If I was in the same situation again, I'd send a followup letter, call, keep persisting until they replied.
So let me encourage you not to take it personally, but to keep trying, and don't write off an order just because they don't answer you for a while. It's easy to assume they don't care or don't like you or aren't interested, but I'm convinced the real reason is just that they're busy and don't get around to it, and they figure if it's God's will you'll keep trying until contact is established.
If I was in charge, though, I'd sure give vocations a higher priority. I saw an interview with the vocation directress of the Dominicans of Mary, Mother of the Eucharist in Ann Arbor who've grown from four sisters to about a hundred in less than ten years. She said she always takes her Blackberry with her wherever she goes, and answers emails right away. THAT'S the way to do it.
