Some like XCP Wallet (extension) for Chrome work entirely out of the browser.

Hi,

1. I got this while trying to submit Contact Form on blockscan.com:

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

I retried - same issue.

2. About a week ago I had a problem with password recovery on blockscan.com. I think submitted feedback about that as well, but I'll try again. IIRC there's a problem with password reset whereby the site asks for one's email address but doesn't accept it with a message that the username should be provided instead, or something like that.

@mtbitcoin, on home page the exchange rate of XCP is based on the last BTC Sell (for XCP) trade executed on the DEx, which was few days back.
Maybe you should the rate from Coinmarketcap or weighted average from main exchanges?

I think most people aren't tweaking things because they don't know what they mean (but it could be checked of course, by looking at BTC Sell orders, especially expired).

Matches aren't handled in the wallet but below in counterpartyd (which is why counterpartyd can still use BTC Sell although it was recently removed from Counterwallet).

Can you add the field "match_expire_index" from https://github.com/CounterpartyXCP/counterpartyd/blob/master/lib/blocks.py#L318 to table on http://www.blockscan.com/order_match.aspx?

Because it's not easy to figure out when one's order was matched.

2,648,527 XCP

Look up what "deterministic wallet" means.
You used a wrong pass phrase.

You mean the testnet faucet?
I don't know what you mean by "your current one in your profile" (what profile?).
You need to use the testnet Counterwallet where you create a new wallet with "fake" XCP's that you get from the faucet.

Who are "they" who are charging you those fees?

Nothing is compounded and it's not a "fact". Your XCP haven't been paid to anyone, so of course they can't be refunded.
Pending a payment, tokens are held in escrow and only if payment from both sides can be executed the protocoll executes a transaction.
Otherwise as PhantonPhreak said if the other side doesn't send the money your order expires.

If you looked at your order status (inside of CW) or at Blockscan.com you could have seen this yourself.

The devs are working to make it better and if anyone can offer realistic examples of improvements that can be implemented, let them know here or on Github.
Traditional exchanges are one of faster options for centralized XCP/BTC trading: https://www.counterparty.co/xcp/ has a list.
