Hi guys

I'm not sure this is the right area of SRP to address a small issue with the site.
When I go to the "Razors" section and look at "Reviews of Razors" I find I cannot post there.

I see a sign in box, but when I enter my user name and password in the relevant place I get a message stating I have used an invalid user name and password.

Following instructions in the box to press the back button and try again results in the same thing happening.

I also get the message that says I am on attempt 1/5 to sign in, or more if I tried a few times.
If I get to 5 attempts and fail I will be denied access for 15 mins.

Is there a fix around this issue so i don't get it all the time.
I would really like to be able to post and ask questions there.

Thanks for any help you can give
