Given how negative you guys have been toward each other lately, I wonder if I should even post this? Aw well, I am not got going to withhold information from people just because of a few ungrateful people, that would be too selfish of me.(hint hint)
Anyways, I had no problem paying citi with $100 of a $500 us bank MasterCard just now.
Therefore, i cannot really provide any insight as to why some of you were having problems,or whether the issue may have been fixed. Again, I had no issues just now

As I said earlier some of you need to be more polite here to fellow members and/or others
In order for this community to continue to effectively function. We all should understand that ALL MS methods involve risk (however minimal) if you are NOT willing to accept this then Do Not engage in.MS. Yes flyertalk and fellow members are a sort of support group for us all, providing help and advice for us in times when we screw something up while MSING but that's pretty much it and we should be ok with that. Frankly, I just find it disheartening and somewhat cowardly even, when people start blaming everyone but themselves the second they do something wrong or an MS method stops working. Man up and remember, you have nobody to blame for YOUR financial decisions but YOURSELF
