Hi, Joseph:
When you have changes to make in a promotion, go to one of your Threads and post. Then go to your first post and made additional changes to reflect your special promotion, etc. - such as price change or promotion code, for example. If you need the Title of your Thread changed, contact me via PM. Regardless, whenever anyone makes a new post, the Thread will jump to the top of the que. (This is one reason why some authors (those who do not follow the Posting Guidelines make spammy bumps to their Threads. This is a wrong thing to do, and many Members here don't like it. Neither do I).
As you can see from the previous posts, our readers pretty much don't like spammy Threads - no matter how well-intentioned an author may be.
Also, as you can see, our Readers are very encouraging about Members' writings, and wish you only the best.
Please also visit (as I mentioned before), my "Shameless and Endless" Thread: It specifically has a lighthearted tone - one that I've worked hard at maintaining.
However, the real success of that Thread belongs to the contributors who post there. The contributors understand the "in joke" of the Thread's purpose and seem to thoroughly enjoy posting and posting and posting about their favorite topic:
Their own work. 
If you have any questions, please don't hesitate to PM me.
Don
