Welcome to MTT!  We are always happy to see an influx of new authors - after all - we were all new once ourselves.

One of the things I enjoy most about fanfic is eagerly anticipating the next chapter of a work in progress.  It's a great way for a new author to gain a following. 

However, in my years as an archive admin I can confidently say I have learned that quantity is not always quality.  It most certainly can be but more often than not - an author pulling his/herself in too many directions causes the overall work to suffer. 

Focusing on one story at a time helps to showcase your best work.

I completely understand that it is so easy to get caught up in the excitement of posting a new fic.  As I said - I was there once myself.  But it is not only better for you as an author (in terms of getting feedback) - it is sort of unwritten protocol not to flood the archive by posting multiple fics at the same time.

It's important to remember that everyone is looking for their chance in the spotlight.  New authors AND those who have been at it awhile all thrive on feedback and exposure to the members of the archive.  It's important to give everyone a fair chance.

Just some food for thought.
