Post any SS501 fanfiction that you can find. However, refrain from posting fanfictions from other forums, as not all of our members may be members there. Stick to places where anyone can view them regardless of whether they're regular visitors or members. For example, Fictionpress, Winglin, etc. all work well.

(I go under the name of love501 here, so don't be alarmed!)
Send in your findings, please!
