The linked site is an application for sending and discussing links with your friends, not for exchanging money. I think the distinction is quite clear.
IANAL, but it doesn't appear that you infringe on anything. A trademark is only valid for products or services which appear to be, or are similar to, the scope of registration. This can include scope for 'natural growth' into other areas.
All their trademarks seem specifically about the exchange of currency. There is nothing there relating to sharing and discussing links with your friends, or even broader classification which they could most certainly have registered for.
That said, you should speak with someone a lot more knowledgeable than me about it!
The site doesn't say a lot, so I can only guess, but the only way this could be useful or at least add something new would be to not require the receiver to use the app (receive by mail, by fb message, etc) and to add semantic (e.g. tags) and archiving (kind of social shared bookmarks?) capabilities.
Or maybe it's just an early released MVP not to be taken very seriously. I hope it's this last option, as I don't see no added value so far.
That way we won't have to disturb each other for being late to the party.
I think you have a bit of a problem with whatever system you are using to send notifications!
