guest writing

Hi everyone,I have a question about guest post,and want to get some tips from you. I know how to find nitch guest post sites,but I dont know how to get my articles published quickly.sometimes I submitted my articles,but there is no response.Could you give me some tips? Many thanks.:)

Any opinions about guest blogging? Is it worth all the hustle only for a backlink? should i use blogsynergy or guestblogit?

I have a few people looking for posts in exchange for links as I run a newly opened guest blog community. I also have fresh content available for someone elses blog. If anyone would like the address to join and see if it is worthwhile to them then please pm me. It would also make my forum larger...
